Embodiment Construction

[0030] In order to further understand the content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0031] The structure of the DCS system experiment platform for the process control research using the semi-physical simulation technology required for the realization of the present invention is as follows: figure 1shown. The DCS system experiment platform fully meets the important idea of ​​"decentralized control, centralized management", and adopts a layered flat functional structure in the overall design. It is mainly divided into three layers, which are system monitoring management layer, field device control layer and process data acquisition layer. The system monitoring management layer consists of engineer station, operator station, and data server using industrial Ethernet switches, which are used to complete DCS system development and process...

Abstract

The invention discloses a data collection system (DCS) and an information processing method of a computer production simulation model. According to the information processing method of the computer production simulation model, communication modes of different protocols such as an industrial Ethernet communication technology, a process filed bus (PROFIBUS) communication technology, a multi point injection communication mode and an organic photoconductor (OPC) communication technology, wherein the industrial Ethernet communication technology is responsible for an engineer station and an operating personnel station of the DCS system and data exchange between a data server and a controller of the DCS system, the MPI communication technology is responsible for data exchange between each subsidiary controller of the DOS system and a corresponding OPC server, and the OPC communication technology is responsible for data exchange between the OPC servers and the corresponding computer production simulation models. By means of the information processing method of the computer production simulation model, the DCS system is directly or indirectly connected with the computer production simulation model through different communication protocols, and therefore the purposes that process data in the computer production simulation model is accurately and quickly acquired and instruction of the controller is transmitted to the computer production simulation model can be achieved.

Description

technical field [0001] The invention relates to communication technologies such as industrial Ethernet technology, field bus technology and OPC. More specifically, it relates to a DCS system and a computer production simulation model information processing method. Background technique [0002] DCS system has been accepted and developed by many industrial fields at present, and various colleges and universities are also carrying out DCS system experimental teaching work one after another. The DCS system introduced by the factory cannot be put into production directly, which involves some related issues such as functional testing and verification of the DCS system. Universities and colleges cannot provide large-scale production process unit as the controlled object of DCS system due to the limitation of environment and cost. Therefore, the DCS system in the laboratory is useless due to the influence of the objects in the factory production process. [0003] In recent years,...
